Hi,
I previously designed an amplifier PCB that included the output relay on the PCB. I want to redesign the board for through hole components, which take more space than the surface mount transistors previously used. The board dimensions need to stay the same to replace the existing board since the heat sink has been drilled etc.
If the relay(s) are off the board, i can reclaim more space for the circuit, and use through hole components, change the relay configuration by design, and also it will be easier for maintenance of any failed relay.
Does anyone have a preferred option, as off board protection relays offer greater flexibility for very little degradation, if any, for on board relays.
Thanks and regards,
Shadders.

I would put the relay off board. Easier to service if needed. Second, I like symmetrical pcb layout’s, this would be difficult if on board. Grounding can also be easier… depends where you make your star gnd point.
Off topic: since I’ m using a SSR output relay, I will not use electromechanical relay’s again!
